Xulin Pen

[Jachin2012]

I received my new Xulin pen recently and trued it the other day. It is very hard to press the button to inject the test subject, surprisingly hard to press. Is this normal? It’s so hard to press I’m kind of put off to using it, it make pinning with a syringe seem much easier. Please share experiences.

I have bought the basic pens on Amazon from different vendors not the Xulin tho , but i have noticed diff pens have a different feel when administering the dose although the all look basicaly the same and costs aprox equal as well. I've not tested the accuacy yet

I was thinking the same thing. One of my pens is tough to push, the other was pretty smooth. Not Xulin, but both were equally smooth without the vials inserted. I switched the vials between them and the problem followed the vial.

I found the one with GHK-Cu to be tough to inject. The one with M1 was smoother in both pens. I believe, but I’m not certain, that the vials were from the same batch.

So one of two things seems likely in my case. One vial was tighter than the other, or that the contents have different lubricity, thus making a difference in the force needed for injection. GHK-Cu vs. Melanotan 1 vs. Triz.

The Triz is in the Gansulin auto pen, but I might switch it around.

It may be the vials.

Vials make the difference… also the finer the needle, the harder it will be to press.
I had the Xulin from here and it was smooth. I gave it to my friend and she loves it for her Tesa.
The vials make such a hige difference. I have shitty vials, but they are smooth. Bit some good vials are a little harder.
